CHICAGO (CBS) —  Police are investigating after a 3-year-old boy shot himself in the foot in Chicago’s Rosemoor neighborhood Friday.

Police say it happened after he found a loaded gun in an upstairs apartment on 103rd and Calumet.

An unnamed woman in her 20s drove the boy to Roseland Hospital.

Someone who works there called 911, and that is how police learned there had been a shooting.
